12 Claims. (01. 105 41s) This invention relates to car construction and of front and rear door posts l2 and I3 and a is concerned primarily with the securement of floor I l. The door posts are of the well known greater strength of side sills for railway house AAR type and are generally channel-shaped in cars, particularly at the door openings in such section. The front door post I2 embodies a ar longer leg l5 to which metallic sheathing I6 is The standard AAR construction for railway fastened, a web I1 and a shorter and inwardly house car embodies an angle side sill having undisposed leg l8. Similarly, the rear door post I3 equal legs. The larger of the legs is arranged embodies a longer leg 19 to which the metallic vertically and provides means to which the car sheathing I6 is secured, a web 20 and an inwardside posts and the metallic sheathing are sely disposed shorter leg 2|.

A door opening H formed in the It will be apparent that numerous changes and side wall of the car is defined in part by means modifications in the details of the invention will be clear to those skilled in the art. It is intended, therefore, that all such modifications and changes be comprehended within this invention, which is to be limited only by the scope of the claims appended hereto.

I claim:

1. In a railway house car having a floor, spaced door posts, a side sill, said sill having an upstand-, ing leg extending substantially from end to end of said car, said leg from said posts to the ends of said car extending above sa'd floor, said leg being flanged between points adjacent to said posts, said flange gradually sloping "downward and inward from said points to said posts and being horizontal from post to post, said horizontal portion of said flange being adapted to lie upon said floor, and means securing said posts to said sill.

2. In a railway house car having a floor, spaced door posts, a side sill, said sill having an upstanding leg extending substantially from end to end of said car, said leg from said posts to the ends of said car extending above said floor, said leg being flanged between points adjacent to said posts, said flange gradually sloping downward and inward and progressively increasing in width from said points to said posts, said flange being horizontal and of uniform width from post to post, said horizontal portion of said flange being adapted to serve as a threshold plate for said floor, and means securing said posts to said sill.

3. In a railway house car having a floor, spaced door posts, a side sill, said sill having an upstanding leg extending substantially from end to end of said car, said leg from post to post being turned downwardly and inwardly to provide a threshold plate for said floor, and means securing said posts to said sill.

4. In a railway house car having a floor, spaced door posts, a side sill having an upstanding leg and an inwardly directed leg extending substantially from end to end of said car, a reinforcement for said sill having an inwardly directed leg, means securing said inwardly directed legs together, said upstanding leg from post to post being turned downwardly and inwardly to provide a threshold plate for said floor overlying said inwardly directed leg of said sill, openings in said threshold plate to permit securement of said inwardly directed legs by the means therefor, and means securing said posts to said sill.

5. In a'railway house car having a flooryspaced door posts, a side sill having an upstanding leg and an inwardly directed leg extending substantially from end to end of said car, a reinforcement for said sill having an inwardly directed leg, means securing said inwardly directed legs together, said upstanding leg from said posts to the ends of said car extending above said floor, said upstanding leg being flanged between points adjacent to said posts, said flanges gradually sloping downwardly and inwardly from said points to said posts and being horizontal from post to post to provide a threshold plate for said floor overlying said inwardly directed leg of said sill,

openings in said threshold plate to permit securement of said inwardly directed legs 'by the means therefor, and means securing said posts to said sill.

6. A side sill comprising an intermediate channel-shaped portion, end portions each embodying an upstanding leg extending above said channel-shaped portion, and portions sloping downwardly from said upstanding legs to said channelshaped portion.

7. A side sill comprising a horizontal leg and a vertical leg, said vertical leg being gradually turned downwardly toward said horizontal leg at spaced points to provide sloping flanges and a horizontal flange connecting said sloping flanges, said horizontal flange being spaced from said horizontal .leg.

8. Aside sill comprising a horizontal leg and a vertical leg, said vertical leg being gradually turned downwardly toward said horizontal leg at spaced points to provide sloping flanges and a horizontal flange connecting said sloping flanges, said horizontal flange being spaced from said horizontal leg and being formed with a plurality of openings therein, for the purpose set forth.

'9. A side sill comprising an intermediate channel-shaped portion having upper and lower flanges, end portions each embodying an upstanding leg extending above said channel-shaped portion, said upstanding legs being gradually turned downwardly to form a sloping flange of progressively increasing width, said flange bein integral with the upper flange of said channelshaped portion.

10. Ina railway house car having a floor, spaced door posts, a side sill, said sill having an upstanding leg extending substantially from end to end of said car, said leg being flanged downwardly between a point adjacent to one of said posts and a point adjacent to the other of said posts, said flange gradually sloping downward from said points substantially to said posts and being horizontal substantially from post to post, and means securing said posts to said sill.

ll. A side sill comprising a horizontal leg and a vertical leg, said vertical leg being gradually turned downwardly at spaced points to provide sloping flanges and a horizontal flange connecting said sloping flanges, said horizontal flange lying in a plane above said horizontal leg.

12. A side sill comprising an intermediate portion having upper and lower horizontal flanges and a vertical web, end portions each embodying an upstanding leg extending above said intermediate portion, said upstanding leg of each end portion being gradually turned downwardly and forming a sloping flange of progressively increasing width, said flange being integral with the upper flange of said intermediate portion.
